PLANTER AND CULTIVATOR.

Specification of Letters Patent.

Patented J an. 27,1914.

Application filed March 24, 1913. Serial No. 756,525.

To all whom it may concern Be it known that I, GRovER C. KNIGHT, acitizen of the United States, residing at Grove, in the county ofDelaware and State of Oklahoma, have invented certain new and.

useful Improvements in Planters and Cultivators, of which the followingis a specification, reference being had to the accompanying drawings.

This invention relates to new and useful improvements in agriculturalimplements and more particularly to that class known as corn planters.

It is a well known fact that corn planters, no matter how eflicient intheir use, occasionally fail to plant a hill of corn. This only becomesknown to the farmer when the corn commences to sprout. times occurs thatthe corn has become injured and will fail to sprout, which causes afurther irregularity in the spaces between the hills.

The object of this invention is to overcome this disadvantage in cornplanting by the provision of an attachment which can be applied to acultivator for the purpose of replanting these dead hills.

Another object of this invention is the provision of a corn planter suchas described, which is adjustably and removably supported by acultivator, and which can be operated to replant the dead hills, whilethe corn is undergoing the first cultivating process.

A further object of this invention is to improve and simplify devices ofthis character, rendering them comparatively simple and inexpensive tomanufacture, reliable and efficient in use and readily operated.

Figure 1 is a side elevation of my inven tion; Fig. 2 is an enlargedlongitudinal sectional view thereof, showing the planting foot loweredin full lines and raised in dotted lines; Fig. 3 is a detail view of aportion cured thereto a vertically movable support-.

Furthermore, it ofting bar 14, which is held rigid thereon by means ofthe clip 16. A horizontal bar 17 is attached to the vertical bar 14 inspaced relation from the lower end thereof and supports a seed hopper 18formed in its lower end with an opening 19, which registers with theopening 20 formed in the rear extremity of the bar 17. A guide plate 21is secured to the under side of the bar 17 and is formed with an opening22, equal in size to the open ings 19 and 20, but located preferably inad Vance thereof. A sliding feed bar 23 operates between the lower sideof the bar 17 and upper face of the plate 21 and is formed with anopening 24 adapted to register with the openings 19 and 20 and theopening 22 for a purpose to be later disclosed.

A shaft 25 is journaled transversely of the bar 14 and has keyed to oneend thereof upon one side of the bar 14 an operating arm 26, which isconnected by a link 27 to the forward end of the sliding bar 23, whilesecured to the upper end of this arm 26 is an operating rod 27, whichhas its opposite terminal movably secured as at 28 to one of the handles11, at which point the said rod 27 is equipped with a finger grip 29 bymeans of which the same can be moved longitudinally of the cultivator10, for the purpose of revolving the shaft 25. Obviously, as the arm 26is moved inwardly, the sliding bar 23 will be moved inwardly until theopening 24 registers with the openings 19 and 20,

which permits a certain portion of the contents of the hopper 18 toenter the opening a 24 and obviously as the rod 27 is moved forwardly,the seed contained within the opening 24 of the bar 23 will be movedforwardly until the opening 24 registers with the opening 22, at whichtime the seed will be dropped through the opening 22. A planting shoe 30is disposed below the opening 22 for receiving the seed dropped from theopening 24 in the bar 23,'and is pivoted at its inner end to the arms 31and 32, the former of which is keyed to the shaft 25 while the latter ispivoted, as at 33, to the lower end of the bar 14. A spring 34 connectsthe arm 32 with the bar 17, for normally holding the shoe 30 in itsraised position and in contact with the under side of the plate 21.

lateral extension 40, which projects through an opening 41 in theforward side of the shoe 30 for contact with a trip finger 42, which iscarried by the arm 32.

5 A spring 43 connects the lower arm of the bell crank lever with theshoe 30 above the lateral extension 40 and serves to normally retain themember 35 in its closed position. Obviously, however, upon thedepression of the shoe 80, the trip finger strikes the offset end 40 ofthe lever 38, which forces the lower end of the lever 38 downwardlythrough the medium of the link 37 forces the closure 35 downwardly, thuspermitting the contents of the shoe to drop therefrom through the lowerend thereof.

The operation of the device is as follows :After the bar 14 has beenproperly adjusted to its proper position upon the bar 13, and heldthereon against displacement by the clip 16, the person using themachine cultivates the field of corn in the usual man ner. hen, however,he comes upon what has been termed a dead hill, he moves the machineuntil the shoe is disposed thereover, and then draws the rod 27rearwardly, which causes the depression of the shoe 30 and the operationof the closure to plant additional seed in the dead hill.

30 As the shoe 30 is moved downwardly, the sliding bar 23 receives asupply of seed from the hopper 18 and as the rod 27' is moved forwardlyagain, this bar 23 moves forwardly and drops the seed into the plantingP5 shoe 30, where they are held by the closure 35 until the rod 27 isagain moved rearwardly.

It should be noted in this connection that various minor changes in thespecific details of construction can be resorted to within the scope ofthe appended claims without departing from or sacrificing any of theadvantages of the invention.

From the foregoing description taken in connection with the accompanyingdrawings, it will be manifest that a corn planter such as described isprovided which will fulfil all of the necessary requirements of such adevice.

Having thus fully described this invention, what I desire to claim andprotect by Letters Patent is 1. In a corn planter, the combination witha vertically movable support, a hopper carried thereby, a planting shoeconnected to the support and vertically movable relatively thereto,means for conveying seed from the hopper to the planting shoe, a closurewithin the planting shoe, and means for simultaneously moving theplanting shoe downwardly and operating the closure therein, as and forthe purpose described.
